Drawing on AnaSpec's expertise in detection reagents, the Italian scientific journal, PharmaChem, has published a technical article by AnaSpec regarding the uses of FRET technology for the screening of proteases. The article describes the biological roles of proteases, the use of FRET technology for the study of proteases, and highlights the growing need for high-performance FRET pairs like 5-FAM/QXL™ 520 (AnaSpec's proprietary quencher).
